PANEL-BOARD AND FUSE-HOLDER.

SPECIFICATION forming part of Letters Patent No. 660,113, dated October 23, 1900.

A plicatio fil d March 14, 1900. Serial No. 8,602. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES J ULIus KLEIN, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Panel-Boards and Fuse-Holders, of which the following 'is a specification.

My invention relates to panel-boards and fuse-holders adapted for use therewith.

In the accompanying drawings I have shown a panel-board and fuse-holders which illustrate myinvention, it being understood that the details may be varied without departing from the spirit of my invention, which is concisely defined in the claims.

In the drawings, Figure 1 is a plan view of a panel-board constructed in accordance with my invention. Fig. 2 is a sectional view there- 'of, showing a sliding fuse-holder in place, the

section being taken on line 2 2 of Fig. 1. Fig. 3 is a sectional view of the panel-board on line 3 3 of Fig. 2, the fuse-holder being shown in end elevation. Fig. 4 is a plan view of the fuse-holder. Fig. 5 is a plan view of the fuseholder with the cover removed to show the interior arrangement. Fig. 6 is a section on line 6 6 of Fig. 5. Fig. 7 shows a side elevation of a means for imparting a snap movement to the sliding fuse-holder, and Fig. 8

shows a swinging fuse-holder.

The main objects of my invention, briefly stated, are these:

First, to decrease the width or size of the panel-board and at the same time separate the opposite terminals of the branch circuits as far as possible. This I do by mounting the bus-bars edgewise and in two-wire systems mounting the like terminals of the branch circuits upon the same side of the bus-bars.

40 Second, to improve the construction of the removable fuse-holders and to bridge all the bus-bars and effect direct connections from the working bus-bars to the branch-circuit terminals.

5 In the drawings, 1 represents the slate base of the panel-board, and 2 3 4 the bus-bars. These bus-bars are suitably secured to the base, preferably, by bolts 5. These bus-bars are set up edgewise to the slate base and may be provided with suitable binding-sockets 6.

knife-switches is thus avoided. All the terminals 10 on one side of the board may be of one polarity, and similarly all the terminals 9 are of the opposite polarity. By this means the distance between unlike terminals of the same branch circuit is increased as far as possible without adding to the necessary size of the panel-board. The circuit connections are preferably made by a movable or removable fuse carrieror holder, of which two forms are shown in the drawings, although this idea is capable of great variation without departing from the spirit of my invention.

In Figs. 2 to 6, inclusive, I have shown a form of sliding fuse-carrier which bridges all the bus-bars and carries the fuses. The rigid body 11 or block of the fuse-holder or fuse-carrier is suitably recessed to receive fuses, connections, &c., and in the use of the terms f use-holder or fuse-carrier equiv- 8o alent means for carrying clips and completing a circuit are also to be understood, as my invention is not limited to the use of fusecarriers. The vertical apertures 12 receive the guiding-bolts 13, which are fixed in the slate base and serve to guide the fuse-carrier in its up and down movements, which are imparted to it by a suitable porcelain handle 14:, carried upon a screw 15, which is socketed in the block 11. The fuses 15 are carried in recesses 16 of the general shape of the letter Ithat is, they consist of two e11- larged recesses in which binding-terminals 17 are seated, united by a narrow passage in which the fuse 15 is located. These recesses are covered in use by suitable insulatingplates 18 and the whole covered by a cover 19, having spaces 20 for a directory, which is required by the fire laws of some cities. This cover is provided with lugs 21, which engage the block 11, and is held in place by the knob or handle 14. The binding-terminals 17 extend through the block 11 and are provided with clips 22, by which term I mean to include any and every means for removably engaging the edge-on bus-bars and making efficient electrical contact therewith.

Two variations of this idea are shown in Fig. 2, wherein the clips 22, engaging the bus-bars 2 and 4, embrace the same, whereas the clips 22 embrace the bar 3 and one of them is wedged in between the bars 3 and S. In the form of the structure shown the block 11 is represented as provided with clips 22, carried upon a terminal binding-screw 23, which is connected to the fuse by a wire 24:, lying in a engage the bus-bars with sufficient force to Of course I do not limit myself to employing a sliding fuseretain the block in place.

holder, but may use other forms. For instance, in Fig. 8 I have shown a fuse-holder;

hinged to standards 26, of which only one is shown. Suitable means may likewise be provided to insure a snap action in either form of fuse-holder. shown the fuse-holder as provided with a rounded portion resting between springs 27, mounted on the base 1. Other forms of snap action may be used.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a panel-board, the combination of busbars having edgewise mounted portions adapted to be engaged by a clip and a device for bridging and connecting the bus-bars in circuit consisting of a body carrying clips adapted for engagement with the edges presented by the bus-bars.

2. In a panel-board, the combination of an insulating-base, bus-bars mounted edgewise thereon, and a movable circuit-connector consisting of a body provided with clips adapted to removably engage the edges of the said bus-bars to make electrical connection therewith.

3. In a pan el-board, the combination of busbars comprising metallic strips mounted edgewise on the panel-board and circuit-terminals likewise mountedupon the said panel-board on opposite sides of the group of bus-bars, and a circuit-connector having clips adapted for engagement with the bus-bars, bridging the said bus-bars and connecting the same to the appropriate branch-circuit terminals on opposite sides thereof.

4:. In a panel-board, the combination of an Fol-instance, in Fig. 7 I have insulating-base, bus-bars mounted edgewise thereon, one of the said bars havinga rei n forcing-strip 8 also mounted edgewise and in electrical connection with the said bus-bar and a movable circuiteon nector-provided with clips adapted for engagement with the bus-bars.
